Print failed on last layers
Hi, I took a bigger print with my Vcore 400 for the first time last night. In the last layers, it failed completely. There was no adhesion on one side anymore. However, in terms of dimensions, the part is correct. But you can already see some errors beforehand. What could that be? Too low temperature? Flow rate too low? Humidity? The printer is an open Vcore 400, the slicer is Orca, and the material used was XPETG from extrudr at 220°C.

What was your bed temp? 220 seems really low for petg - the print is not completely matte yet but this is usually sign of low temperature - my experience from petg, not sure how the Xpetg is different.
I started printing 300mm+ petg prints enclosed at 40C chamber temp because I experienced some warpage as well.
Petg also has some small shrinkage (approx 0.35%). It is not much so we usually do not have to take that into account but for large prints it is enough to possibly cause the same warping as with ABS
